Parapapillary drusen of the retinal pigment epithelium

Acta Ophthalmologica, 2023
AbstractPurposeTo describe the occurrence, morphology and associations of parapapillary drusen of the retinal pigment epithelium (RPE‐drusen).MethodsUsing light microscopy, we histomorphometrically examined enucleated human eyes.ResultsThe study included 83 eyes (axial length: 25.9 ± 3.2 mm; range: 20.0–35.0 mm). Eyes with parapapillary RPE‐drusen (n =

MsTGANet: Automatic Drusen Segmentation From Retinal OCT Images

IEEE Transactions on Medical Imaging, 2022
Drusen is considered as the landmark for diagnosis of AMD and important risk factor for the development of AMD. Therefore, accurate segmentation of drusen in retinal OCT images is crucial for early diagnosis of AMD. However, drusen segmentation in retinal OCT images is still very challenging due to the large variations in size and shape of drusen ...

Drusen of the Optic Disk in Retinitis Pigmentosa

American Journal of Ophthalmology, 1987
To clarify the nature of mulberry-like excresences of the optic disk, we histopathologically studied the eye of a 66-year-old woman with retinitis pigmentosa. Examination showed that the optic nerve excresences were ordinary drusen and not hamartomas. There was a marked predisposition to mineralization of other intraocular structures.

DISAPPEARANCE OF DRUSEN AFTER RHEGMATOGENOUS RETINAL DETACHMENT

RETINAL Cases & Brief Reports, 2010
To describe the disappearance of drusen after rhegmatogenous retinal detachment.Descriptive case report.A 72-year-old man with confluent subfoveal drusen developed a rhegmatogenous retinal detachment and subsequently improved in vision with disappearance of the subfoveal drusen less than 1 month after repair.Rhegmatogenous retinal detachment can result

New developments in retinal drusen

Ophthalmic and Physiological Optics, 1998
SummaryRetinal drusen are an important manifestation of age‐related maculopathy, and increase with ageing. Recent studies have shown that gentle laser photocoagulation can lead to resolution of soft drusen and may lessen the high risk of development of choroidal neovascularisation in these cases. Laser induced regression of retinal drusen appears to be

Retinal Drusen and Colour Vision

1984
For drusen situated outside of retina, alteration of π1 and π3 mechanisms gives the evidence that a latent pathologic process is ready to destroy the macular area.

Classification of retinal pigment epithelial detachments associated with drusen

Graefe's Archive for Clinical and Experimental Ophthalmology, 1992
To understand the natural history of retinal pigment epithelial (RPE) detachments (PEDs) associated with drusen, we retrospectively reviewed 125 PEDs that had not undergone laser treatment over an average follow-up period of 28 months. We identified six types of RPE detachments: pseudo-vitelliform, confluent drusen, serous, vascular, and hemorrhagic ...

Drusen of the Optic Nerve Associated With Retinitis Pigmentosa

Archives of Ophthalmology, 1985
Globular excrescences of the optic nerve associated with retinitis pigmentosa have been interpreted as drusen or as astrocytic hamartomas. The histopathologic and ultrastructural findings of globular excrescences of the peripapillary region of the optic nerve associated with retinitis pigmentosa were described in a 22-year-old patient who died in a car
